Flashing Instructions

Charge your phone to 100% and backup all your data

Download the firmware and the necessary USB Drivers from here :

Install the LG USB drivers on your PC

Download the LG KDZ Update Tool and install it on your desktop computer from here :

Make sure the Microsoft XML parser is installed on your PC (it use to be). If it's not, install it from the .7z file you've just downloaded in step 4 then

restart your computer

Remove the battery, wait for 30 seconds then hold the "Volume Down" button and plug the original USB cable supplied with your phone (connect the phone to your PC) till the "S/W Update" appears on the screen.
now insert the battery and release "Volume Down" button

Let windows load the USB drivers, wait until it finishes completely

Unzip and Run the KDZ Update Tool (from step 4) as Administrator

Run Windows Enabler (from step 4) as Administrator and click on its icon in windows notification area on your task-bar to turn it on

Configure Type=3GQCT and Phone Mode=DIAG

Pick the firmware (.kdz) file you downloaded in step 2

Click on “Launch Software Update” button and wait for completion (it will take some time about 8-12 minutes , do not interrupt this process or you may brick your phone)

Wait until this lines appears
"1421 : CDMA: wParam = 2004, lParam = 99
1421 : Model Dll Msg Not Found(2004, 99)
1423 : CDMA: wParam = 2004, lParam = 100
1423 : Model Dll Msg Not Found(2004, 100)
1423 : CDMA: wParam = 2001, lParam = 0
1423 : Model Dll Msg Not Found(2001, 0"

When the update is complete, you'll read "Finished" in the log dialog of the Update Tool. Your phone will then reboot into the new firmware version (the first boot will take longer than usual)

If you did everything correctly, your phone must boot into the new software version. Enjoy the new features and share your experience in the comments section below!

Each time that I check for the update with the software update tool on my phone it says that a new version of the OS is available but it requires a connection to the pc and blah blah blah. Then I press Ok and another message appears and it says: "You are currently using the latest software version in current OS version." WTF?
Any idea about when the update is coming to north america?

Finally it's arrived in India. I have updated but missing Qslide feature.

I think its already released in most of the country please check your LG mobile tool or LG PC suite.

As usual, Middle East gets the shaft for updates. Waiting patiently for LG to hopefully provide the update sooner rather than later.
